WILLIAM KEARNEY, OF BELLEVILLE, NEW JERSEY.

IMPROVEMENT IN VAHLVES FOR WATER-PIISES.

Specification forming part of Letters Patent No. 57,920, dated September11, 1866.

To all lwhom it may concern:

Beit known that I, WILLIAM KEARNEY, of Bellevillc,.in the county ofEssex and State of New Jersey, have invented a new and Im proved Valvefor Water-Suppl y Pipes and I do hereby declare that the tollowing is afull, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part ot' this specitication, in which-Figure lis a vertical section of my invention, taken in the line z.00,Fig'12; Fig. 2,-a vertical section ot the same, taken in the line yy, Fig. l.

Similar letters ot' reference indicate corre- .sponding parts.

Theobject ot' this invention is to obtain a valve for water-supply pipeswhich will not be rendered inoperative by means of stones, sticks, orother foreign substances interposin g themselves between the valveaudits seat.

The invention has also for its object the ready starting ofthe valveunder a heavy pressure ot' water, anda quick or rapid movement ot'"thevalve after the same has been started, and a provision made for theescape ot' air from the valve-chest, and to prevent the freezing up ofthe valve in its chest.

A represents a box, provided at each side with a tubular flange, B, towhich the watersupply pipe is connected. The box is of a widthcorresponding internally to the width ot' the valve C, the lower part ofwhich is circular, as well as the lower end otl the box A, (see Fig. 1,)and the box A extends down below the lian ges B B sutticientl y far toallow the valve to be moved down below thc iianges, and allow the freepassage ot the waterthrough the pipe.

The valve, when raised, lits snugly between the inner ends of the twoflanges, and eft'ectually stops the flow of water through thesupply-pipes.

The valve C is raised and lowered, opened and closed, by means of ascrew, D, which passes through the top ot' the box A, and works in anut, E, in the valve, the upper part of the screw-rod working in astuttingbox, F, on the boxA, and having a square formed on it to receivea crank.

0n the upper part ot' the screw-rod there is littcd a worm-wheel, H,into which a screw, I, is made to gear, when necessary, said screwhaving its bearings in bars J J, which are secured by pivot-bolts to thesides of the box to admit of the engagement ot the screw l with theworm-wheel and ot' its disengagement therefrom.

may be applied directly to the screw D, which will, of course, move itwith greater speed, the screw I being previously thrown out from theworm-wheel H.

When the valve C is fully opened it is in the lower part of the box A,and beyond the action ot' frost, being Jtoo far below the surface of theground 5 and in order to prevent the lower part of the box becomingfilled with dirt, I have a tube, a, inserted in the lower part ot box A,provided with a cock, b, having a rod, c, connected to it, which extendsupward to the top of A, so that the valve may be opened to'allow dirt,air, Ste., to escape, which might otherwise prevent or materially retardthe passage ofthe valve into the lower part of the box. This arrangementprevents sticks, stones7 or other foreign substances from interferingwith the closing of the valve, because the valve closes by rising ormovi-ng upward, and any obstruction resting upon it when open or downwould be raised as the valve is raised and be thrown to one side underthe action ot' the water in the pipes; and the innerI oritices ot' theiianges B B are provided with packing d, to prevent substances notdissolved in the water from passing down into the lower part ot' the boxA.

Having thus described my invention, I claimv as new and desire to secureby Letters Patent- The combination and arrangement ot the valve C, boxA, anges B B, cock l), screw D, worm-wheel H, and screw I, all arrangedto operate substantially in the manner as and for the purpose specified.

WILLIAM KEARNEY.
